Electric-cylinder-driven modular robot transportation platform

Abstract

The invention relates to an electric-cylinder-driven modular robot transportation platform. The electric-cylinder-driven modular robot transportation platform includes two or more robot platform units, wherein each robot platform unit includes a robot wheel-leg mechanism and wheels, wherein the robot wheel-leg mechanism is a seven-rod two degree-of-freedom connecting rod mechanism including two sliding pairs, and includes two closed loop; and the wheels are arranged on the robot wheel-leg mechanism. The modular robot transportation platform replaces an existing flat car hydraulic transmissionsystem by connecting rod transmission and the two sliding pairs are active pairs and are driven by a servo electric cylinder. Under control of computer programming, the robot wheel-leg mechanism can realize a large space and highly flexible two-degree-of-freedom controllable movement, so as to enable the wheels to have a strong ability to overcome obstacles. Compared with an existing flat car, themodular robot transportation platform shortens the response time, reduces the failure rate, energy consumption and maintenance cost, also greatly improves the intelligent level, avoids the constraints of hydraulic pipelines, is easy to rebuild quickly, and can better meet the requirements of high-precision special transportation operations.

Description

technical field [0001] The invention relates to the field of flatbed vehicles, in particular to a modularized robot transport platform driven by an electric cylinder. Background technique [0002] Flatbed truck is a kind of engineering transportation vehicle mainly used for loading and unloading large and heavy non-detachable goods. Since it adopts road transportation, it does not need to lay special tracks. It has the characteristics of low cost and high transportation efficiency. Compared with other models of the same specification, it can load More goods, so it is widely used in airports, ports, railway stations, factories and large warehouses, and is favored by transport units. However, in the process of engineering application, there are also many engineering and technical problems in the existing flatbed trucks. First, the existing flatbed trucks, especially the modularized flatbed trucks, all use hydraulic transmission systems, which have high energy consumption, low ...

Problems solved by technology

However, in the process of engineering application, there are also many engineering and technical problems in the existing flatbed trucks. First, the existing flatbed trucks, especially the modularized flatbed trucks, all use hydraulic transmission systems, which have high energy consumption, low mechanical efficiency, poor reliability, and are prone to accidents. Oil spill accidents and other issues; secondly, most of the existing flatbed trucks do not have the ability to be reconfigured, and the number of axles is generally fixed after leaving the factory. It is difficult for users to reconfigure and reorganize according to their needs. It takes a long time to assemble the modular platform according to the task, and requires professionals to operate, which seriously affects the work efficiency; moreover, the wheel-leg mechanism used in the existing flatbed truck technology has small working space and poor flexibility. As a result, the flatbed truck has poor obstacle-crossing ability, or even does not have any obstacle-crossing ability. There are also obstacles such as speed bumps on paved roads such as ports and docks. The flatbed truck will inevitably be impacted when passing by, so it is difficult to meet the transportation of dangerous goods. Require
